Application filed'May 2, 1932, Serial No. 608,730,'and in Great Britain August 28, 193 1.

The invention relates to the braking of the usual holding-down device employed has been one in the form of a pivoted catch, ca-

pable of being pushed at its upper end over a 7 part of the spindle, such as over the'wharve or small pulleyattached tosaid spindle, and

whereby thelatter is driven by, means of a.

2:: band passing about such pulley or 'wharve', as understood. When so engaged by the hold ing-down device mentioned, the spindle can-' not be withdrawnfrom its mount or bolster,

but disengagement from said device enables the same to be withdrawn as desired;

According to my invention, in place'of the pivoted catch aforesaid, I employ a holdingclown deviceof a slidable character, or one capable of sliding in a direction across the so position of the axis of the spindle, in and out of action. This device, so capable of lateral movement, passes about the position of the spindle or mount therefor, and is provided with suitable braking material, such as leather, at a part which comes over a portion ofthe spindle wharve or flange thereof, when tliesaid position for holdingdevice ismovcd into down the spindle.

position relatively to the spindleconcerned,

and a downwardly projecting or depending part, the latter capable of being pressed by J 5 the hand or knee, for example, of the oper ator, on which occasion, the horizontal referred to may press against'a flange of the spindle wharve'for braking purposes,"andf so stop the spindle revolving. Braking ma; Q0 terial is provided on a suitable surface of Thebraking member made use ofconsists of a more or less horizontal portion, when inf thebraking'means named, and the improved lIOldIHg-ClOWD device co-operates with said F or retaining or locking the holding-down device in a given position, a.-projection from the depending' part ofthe braking means is capable of entering a cavity or slot in the holding-down'device, for retaining the latter in the holding-down position, on the other hand said projection inayabut against anexternal part of saidholding-down device, for

retaining the'la'tter out of action, as herein described.

The depending part of theibraking means braking means for sobraking the spindle, as herein set forth.

is capable of being-pushed either inwardlyor outwardly, and a further sectional elevation of a portion of a spindle and mount therefor, provided'lor arranged according to" a form of my invention, theparts being in the working position. Fig. 2

projection may be included for limiting its movement.

In the accompanying drawing, Fig. '1 1s a is-a modification of a part of Fig; 1. I Fig. 3

:Fig. 4 isa sectional planfview, chiefly of the improved holding-down device, while Fig. 5 is an'under-plan view in relation tosaid Fig. 1, but chiefly concerned with the" braking means ormember named herein. F1gs. 6 and 'Z are perspective viewsfon an enlarged scale, of the improved holdingdown device, and a-part of the braking mem-j ber, respectively,andreferredto herein. The I spindle, which in the'present example is one suitable for a ring spinning frame, is shown at 1, its attached wharve being indicated at 2. v A part of the Imaohineframing is shown at 3 in Figs. 1 to?) inclusive, and to which the mountfor said spindle is attached in manner indicated, and well known.

According to our invention, the holdingdown device is shown atd in Figs. 1, 3,'and 4,

as well as in Fig; 6, while a modified form is shownat 5 in Fig. 2. "This device. is of a slidablejnaturqor is capable ofbeing'moved 'late ral ly in a direction across t'he position of theaxis' off the spindle 1, when the latter 7 is in its mounted condition, for which sliding purpose the device named is provided with a cavity or slot at 6 (Figs. 4 and 6.)

whereby it is able to pass abouta portion 7 of This slot I being elonthe mount named. That is to say, the device:
